For those running the IX booster.

LOL - I was just following up on e30this's question about the $130. BMA parts search yeilds an entire 5m spool, not the not the seven dollars worth you actually need...

WHOOPS :) sorry bout that!

My parts should be getting dropped off by the dealer today.
we will see.
Did you get your stuff yet dude8383??

still waiting...i order my stuff from BMA so its takes about 3 days to get to me!

i should be getting something today though :)

[e30this]

dude8383, you got your part numbers all wrong.
When the dealer delivered my parts I got a few feet of brake hose and a strainer with float.
I was expectiong a resivor and 2 fittings.
I needed the line though either way but it dont help that I dont have the resivor and fittings.

[dude8383]

haha man i paid for my fuck up as well.

i received the strainer as well...i sent it back to patrick.

34321112399 - expansion tank

34321102282 - fittings for the brake cylinder

1) Are you assuming the existing e30 cap with float etc already on your car is going to fit the new 2002 reservoir? In my case I am hoping it works but have not bought the parts yet...

2) where are you getting the tank and fittings from? special order through BMA? or dealer or another store?

you have listed the elbow fittings, but it is not clear if they come with the right grommets (plugs) attached.
In the picture here it looks like -yes they are attached-

http://www.realoem.com/bmw/showparts.do?model=2233&mospid=47141&btnr=34_0808&hg=34&fg=25&hl=11

but in the picture here it looks like maybe -no they are sepparate-

http://www.realoem.com/bmw/showparts.do?model=2583&mospid=47141&btnr=34_0814&hg=34&fg=25&hl=20

(note also there are two "plug" sizes...)

you can see a (maybe correct) pic of the (maybe correct) grommet part here:

http://www.autohausaz.com/search/product.aspx?sid=1xkcp3ahri0chkuq1remxxng&partnumber=34311121911

and it is probably the same part as here:

http://www.2002ad.com/storeworks/category.cfm?id=8

look for "grommet (brake master cyl), large outside/small inside for elbow"
(there is a similar grommet, without much description, a few lines above)

2002AD sells the grommet also, but do not list the elbow:

http://www.2002haus.com/brakekits.htm

Grommets (2) Required (For Tii Master Cylinder) 34 31 1 121 911

Or does the MC already have grommets that work (if yes, yours maybe ~18 years old and time for a replacement anyway?) and are they close enough to the same size inner diameter?

The 2002ad listing does makes it seem like a special grommet with smaller inner diameter is needed or at least desirable.

3) Finaly, are you getting a new o-ring for between the booster and the MC?

Let us know what you actualy order and where from, and what you actualy receive, and if the old e30 cap fits, etc.
And good luck!

Anyone else who already knows these details, please chime in!

[dude8383]

Hey man,

I haven't received the parts yet so I can't really say. I am aware that the grommet may not fit in the MC because it is smaller in diameter.

I order everything from Patrick @ BMA...

I should be getting this stuff today though so I will chime in a bit later today and let you know how this stuff looks!

If MR 325 could check out the thread and tell us what he used for these pieces that would be a big help as well :)

Hey dude & e30this,
I couldn't wait, so I ordered from Patrick@BMA:

- the reservoir
- 1m of hose (7$) (should be long enough)
- 2 elbow fittings
- 2 2002tii grommets (i.e the ones with smaller holes; they are dirt cheap so
no risk even if these are not necessary; also I assume they fit the e30 MC)

If anyone thinks of anything else helpful, lemme know.
Cheers!

[dude8383]

I just received my reservoir and the fittings.

I'm going to have to order the 2002tii grommets too.

Care to share the P/N's?

Crap, I just noticed an entire other thread on this. You could spend months reading all the stuff here.

See Matt's post #79 of thread "Everything you wanted to know about brake boosters and master cylinders"

As for the right part number for the grommet, you already quoted it, see right above.
Grommets (2) Required (For Tii Master Cylinder) 34 31 1 121 911

However, Matt points out that the stock e30 325i MC will apparently not fit due to mounting difference, although some argue this point. So based on his input, ether get a 325ix MC or upgrade to an e34 or e32 25mm MC. And I don't know for sure if those grommets fit the 25mm MC, but from Matt's other posts it seems like they will.

And while you are in there, maybe a new o-ring for between the MC and the booster (BMA does not stock this part but put one on order for me). Bad news is again you have to choose between an old part (pn on the realoem ix booster page) or the new part for the 25mm MC. Probably both fit... Details all on realoem for whichever way you go.

[dude8383]

Its nice to have this info here as well because this is SPECIFIC to the IX booster :)

Missed the P/N in the previous post...whoops!

I'm going to order the o-ring and the proper fittings today!!

2002ti reservoir: use for both clutch and brake, or use separate reservoirs?

With a 325ix booster and a 2002ti reservoir, it looks like some folks used (or maybe just talked about using) a separate reservoir for the clutch fluid, and some not.
Who is happier with their set-up?
What set-up did you use?
Pictures?
References to posts that I missed?

Edit:
Matt in thread "New Remote Brake Fluid Reservoir Resources" wrote

34 32 1 112 399. Has 3 outputs with one raised for the clutch. It's the perfect remote res. Just check it more often since it's a little small.
Matt

NickP has, in the same thread, a picture from above showing the clutch fluid line heading rearwards from the reservoir

http://www.r3vlimited.com/board/showthread.php?t=68096&highlight=clutch+fluid+reservoir&page=2

MR325 has a pictures on page 1 of this thread (thanks again). The closeup of the reservoir is with the clutch line not installed (a bunch of stuff is not installed), but in the other picture you can see the fluid line connected to the reservoir.

Unless I hear advice to the contrary, I'll assume that using the same reservoir works out just fine...

[Mossman]

I should know tomorrow how 2x home depot $.50 sprinkler T fittings with one of the bungs cut off and epoxied up, and old airline hose running to stock e30 reservoir right next to the fuse box holds up. I hope I don't die!

[jogfrogjog]

any more pics or info on the final part numbers that work? You guys confused me a bit...

MR 325, can you chime in on this? Thanks

[dpgrand]

[jogfrogjog]

forget it,

I got the part numbers from Pelican parts...

you guys have it in here, but it was a little all over the place...

Fittings (90 elbows): 34321102282 x2 <- this is cheaper from the dealership b/c you don't pay for shipping... when I had this in my shopping cart from pelican parts, shipping was ~ $10 more...
Grommets: 34-31-1-121-911-M4 x2
Expansion tank: 34-32-1-112-399-M4
Hose from Reservoir to MC: 21-52-1-163-714-M21

for those of you who dont mind using a non-bmw part here is what i did. I used a dsm resevoir i picked up from the junkyard while also getting my ix booster, and the dsm nipples fit perfectly into the ix/5er MC. I think i paid like 5 bucks
